Increasing elementary school student numeration through problem based learning with realistic approach

The results of observations and interviews at Primary School (SD) Petra Semarang found that grade 5 students were just learning about numeracy in order to prepare for the National Minimum Competence Assessment. Because it is only this year that students learn numeracy, it is assumed that students’ numeracy skills are not optimal. The purpose of this study was to determine the numeracy ability of students in classes using the Realistic Problem Based Learning (Realistic PBL) model to achieve classical completeness, the average numeracy ability of students with Realistic PBL learning was better than the average numeracy ability of students before Realistic PBL learning models and to find out if there were any the effect of independence on numeracy skills. This research method is an experimental quantitative method. The population of this research is the 5th grade students of Primary School (SD) Petra Semarang in the academic year 2020/2021. Sampling with random sampling technique obtained class 5 A as the experimental class and class 5 B as the control class. The results of this study indicate that (1) the experimental class students’ numeracy skills achieved classical completeness, (2) the experimental class students’ average numeracy abilities were better than the control class students’ numeracy abilities, (3) the experimental class students’ average independence character were better than the control class students’ independence character (3) there was a significant effect of student independence on numeracy skills.
